The Browns’ offense ranks 29th in converting third downs, ahead of only the Rams, Cardinals and Jaguars.

Weeden didn’t help the cause in his four starts, posting a league-worst 47.8 passer rating on third downs. In Sunday’s win over Baltimore, It was Campbell who went 4-of-15 on third-down conversions.

“Riverboat Rob” has gone for it a league-high 19 times on fourth down, giving the head coach swashbuckling appeal to players and fans.

Rob Chudzinski’s two fourth-and-1 successes Sunday were as big as any plays in beating the Ravens.

Troubling

The Browns have been repelled nine times when going for it on fourth down.

Going for it on fourth down is a reflection of teams not good enough to win by conventional means. At least, the three teams that have gone for it more than anyone except Cleveland are the Jaguars (17 times), Rams (12) and Buccaneers (12).

Wideout Josh Gordon ranks 16th with 626 receiving yards, despite losing two games to a suspension.

At the end of last year, the top-ranked Brown (Gordon) ranked No. 39.

How tough are the defenses the 2013 Browns have faced?

They have split with the No. 10-ranked Ravens. They have defeated the No. 5 Bengals, the No. 20 Bills and the No. 29 Vikings.

They have lost to the No. 8 Chiefs, the No. 15 Packers, the No. 23 Dolphins and the No. 25 Lions.

Defenses they have yet to face: The No. 7 Jets, The No. 12 Steelers (twice), the No. 19 Patriots, the No. 26 Bears, and the No. 27 Jaguars.

Promising

Campbell is the quarterback now, and even though he came in cold, his passer rating through his first two starts is 106.6.

The yards-gained average in his starts is up only slightly from the season average, to 327.5, but the team believes he did well against the tough defenses of the Chiefs and Ravens, and that he should keep improving as he finds a groove.

Campbell hasn’t played enough to be on the leader board, but that 106.6 is impressive.

The NFL top five: Peyton Manning at 119.4, Aaron Rodgers at 108.0, Philip Rivers at 106.5, Drew Brees at 104.5 and Tony Romo at 100.0.

Troubling

Campbell missed part of a series against Baltimore with bruised ribs, a reminder that his last extended chance to start, with Oakland, ended six games into the season because of a broken collarbone.

With Brian Hoyer out, the only available replacement is Weeden, who has looked as bad as his passer rating, 66.2.

Get this about the Browns' first-down defense.

It ranks No. 1 in allowing 3.72 yards per play. No. 2 is not close. Last year’s NFC champ, San Francisco, led the NFL in first-down defense at 4.32.

Troubling

The defense ranks 31st in percentage of third downs allowed to be converted, ahead of only the Vikings.

Too many third downs have been converted in scoring range. The defense ranks 31st in red-zone efficiency, giving up touchdowns 68 percent of the time when an opponent gets to the 20 or beyond.

Promising

Chris Ogbonnaya is averaging 5.3 yards on 19 runs. Recent signee Fozzy Whittaker shows signs of promise as a ball carrier. Campbell can make key plays with his feet, averaging 6.2 yards on six runs. The coaches have a knack for dialing up reverses and wildcat plays, with former college QBs Marqueis Gray and Armanti Edwards looming as wild-card threats.

Troubling

No. 1 running back Willis McGahee ranks 24th in the league with 100 carries and 41st with 262 yards.

Among the NFL’s top 50 in rushing yards, the seven worst in yards per carry are McGahee at 2.62, Baltimore’s Ray Rice at 2.67, Baltimore’s Bernard Pierce at 2.71, Arizona’s Rashard Mendenhall at 3.05, Indianapolis’ Trent Richardson at 3.09, Jacksonville’s Maurice Jones-Drew at 3.20 and Cincinnati’s BenJarvus Green-Ellis at 3.23.

Rookie sixth-round pick Andre Elington of Arizona has 71 more yards than McGahee in less than half the carries.

If there is a good year to have a bad running game, this is it.

Remember when the AFC North was ground and pound? Current NFL rushing ranks of the division’s run games: No. 19, Bengals; No. 25, Browns; No. 28, Steelers; No. 29, Ravens.

Troubling

Aside from the Steelers and Ravens, the only teams worse than the Browns in rushing are the Saints, Cowboys, Giants, Jaguars and Falcons.

Red-zone rankings indicate coordinator Norv Turner saves plenty of his good stuff for scoring range. The Browns have the league’s seventh-best percentage (61.9) of scoring touchdowns after they drive to the 20 or beyond.
